Calibration sheet
The figure below shows an example of setting up the RANGE7/5 for calibration using the Calibration Set.
Enough space is needed to spread out the sheet.
1280×430 mm
Set the calibration chart in the position
marked on the sheet for the lens being used.
Memo
For RANGE5, place in the
position off the WIDE lens.
Do not touch the front side of the chart with bare
hands. If dirty, wipe the chart clean with a dry
soft piece of cloth.
Scanning is done seven times for calibration.
Position and angle the calibration chart as
indicated in the Calibration Wizard.
Calibration is easy to understand and perform
with the Calibration Wizard. For details, see “5-1.
Calibration” on p. 70 of the Reference Manual.

Calibration base
Calibration should be performed in the following cases:
• Before using for the first time after purchase.
• If the RANGE7/5 has not been used for a few days.
• If the ambient temperature during storage or use is drastically different from the ambient temperature at the time calibration was last
performed.
• If the RANGE7/5 may have been subject to vibrations during shipping or movement.
• To achieve higher measurement accuracy.
NOTE
• The Calibration Chart has been calibrated using the RANGE7/5 unit with which it was shipped. When performing calibration, be sure
to use the Calibration Chart with the same number as the RANGE7/5 body.
• Before performing calibration, confirm that the lens number is the same number as the RANGE7/5 body.
